Those taking their climbing equipment
with them up a popular cliff in Snowdonia have been warned not to stray when coming down again.
Craig Bwlch y Moch near Tremadog has a fence at the top and some people have been climbing over it and leaving the vicinity via farmland.
However, the British Mountaineering Council (BMC) has reminded members it only owns the cliff face and the land at its foot, noting nobody should use this route as a way off, or pass through the grounds of Portreuddyn Castle.
Instead, climbers should descend via two existing recognised routes, it stated, which have been agreed upon with the national park authorities.
The cliff was previously owned by the Williams family, which ran a nearby cafe and gifted the land to the BMC.
Mountaineer Eric Jones took over the running of the "iconic" eating establishment in the 1980s.
The BMC recently produced its own charter advocating guarantees of access for climbers and walkers.
It did this during the debate on the future of England's forests, when extensive opposition to a sale forced the government to drop any such plans.
